Fit4All: Workouts for everyone - Interview with the developer of a fantastic app

Did you have any prior development or coding experience?

I started programming when I was a teenager. I was always fascinated from Jump & Run games so I programmed my own game. It ran on a PC with a resolution of 320x240 and was great fun to play.

What was the most challenging aspect of developing mobile app?

The app uses the most popular workouts from YouTube but they needed to be analyzed according to the muscle groups the train like abs, butt or legs. Physiotherapists have done this task.

Dr. Alexander Rieger started as an indie developer in 1999 with photo effects for Windows computers, winning several awards over the years ( In 2012 he started developing Apps for iOS. Over 1000 photo effects and useful tools like "Paint My Wall" have been released since then ( In 2016 he focused on Android Apps and has reached over half a million downloads with the light alarm clock "Gentle Wakeup" (

Name a few of your favorite apps and reason you love them.

My app Gentle Wakeup wakes me up gently with light, sounds from nature and a nice weather forecast. I love it.

How long have you been working on this app?

I have worked 3 months on the app.

What need of the user did you have in mind when developing this app?

Why pay money for workout apps when YouTube is full of quality workouts with up to 50 million views and 500 thousand likes? We have selected the best workout videos on YouTube and rated them according to the muscles that are trained by it. This ways you can keep your fitness in balance. At the end of the week you have balanced your arms, abs, butt, chest, back, legs and shoulders. It doesn't matter what your current fitness level is. There are workouts for beginners, athletes, overweight people, seniors and families.

In what way do you think your app is better than similar apps on the market? Please describe in detail what innovation you think you bring and what you are proud of in your app.

What makes it different from other fitness apps is that it doesn't offer its own exercises, but integrates the most popular workouts from YouTube with over 50 million views and 500 thousand likes. I am proud that it aims also non-athletes.

What are your future plans and expected features of the coming new versions of this app?

In the next version of the app, a connection with Google Fit and Apple Health is planned.

Staying fit means getting enough exercise every day. If you reach 7 points for each muscle at the end of the week, you will get a bronze award.

Lose weight the natural way

Therefore, you won't find any function in this app that logs your weight, counts calories, or determines your BMI on a daily basis. Don't listen to anyone who promises you a quick weight loss method through dieting. 7-minute workouts are too short a time to stay fit. For a healthy body, you need to change your habits for the long term. You will see the first results after a few weeks.
